    I applied through a recruiter. The process took 1 day. I interviewed at Comcast (Philadelphia, PA) in March 2017.

    Interview

    Recruiter messaged me in Linked. Had a call with recruiter and asked about my current projects, salary, achievements, goals..etc. Recruiter forwarded my profile to hiring manager. Had a 30 min telephonic conversation with hiring manager. It was a high level discussion. Then they invited me for onsite interview at Philadelphia, PA. There were totally 5 interview sessions at onsite. Interviews started at 11 am and finished at 4 pm. It was bit exhausting to face back to back interviews. I was asked to give brief introduction and about projects in each interview. It was bit boring to tell again and again the same. Many white boarding programs.

    Application

    I applied through a recruiter. The process took 1 day. I interviewed at Comcast (Philadelphia, PA) in December 2015.

    Interview

    The interview process consisted of meeting many team leads, including one head of technology. While the total process felt rushed, disheveled and succumbed to the typical 'big business' mentality, the individuals were more than pleasant and intelligent. They allowed Skype interviews, which they seemed to prefer, but did not make this known through the third-party recruitment agency. No one had any idea why I was there.

    Application

    I applied online. I interviewed at Comcast (Phila, PA) in June 2014.

    Interview

    Just awful and absolutely zero information given. Interviewer had no interest in actually conducting the interview which I found highly insulting. Needless to say, I didn't get the job nor did I want it.

    Senior Software Engineer Interview

    Anonymous Employee in Littleton, CO

    Neutral Experience
    Easy Interview

    Application

    I applied online. The process took 2+ months. I interviewed at Comcast (Littleton, CO) in June 2010.

    Interview

    I received an initial phone call from a Comcast recruiter. The recruiter's questions were mostly about career interests, salary expectations, when I would be available, etc. I then received a call from the hiring manager. No technical questions, just questions about what I had on my resume. Next came an on-site interview with two other Senior Software Engineers. One asked almost no technical questions, but the other had put together a list of questions that was about two pages long, mostly pertaining to the Java programming language, APIs, and tools. With about 12 years of Java experience under my belt, I sailed right through these.

    Interview Questions

    • I cannot recall a specific question that stood out as being "most difficult or unexpected", but almost all of the questions could be gleaned from The Java Programming Language or the Java Standard Edition API documentation, for example: "describe the java.util.Arrays class".   1 Answer

    Negotiation

    I was able to get the salary and signing bonus up slightly from the original offer, but everything else was standardized and not easily negotiable. For example, I asked for more vacation beyond the standard 10 days that was offered, but was told that such a concession would require the approval of a senior vice-president, and that such approval was rarely given. In hindsight, I think that it would have been possible to get such approval, but it might have taken a long time to get, and who really has the patience to wait for days or weeks once you have an otherwise good offer in hand?

    Difficult Interview

    Application

    I applied through a recruiter. The process took 3 days. I interviewed at Comcast (Philadelphia, PA) in October 2015.

    Interview

    It was horrible. The person I was supposed to meet was nowhere to be found and I ended up waiting almost an hour before he arrived. After multiple attempts, they reconfigured a test PC for me, but when I kept struggling with the first question, the person examined my environment and stated that I never would've been successful since multiple firewalls were blocking my access. The last straw was that they knew I was focused on software and wasn't an expert on hardware, but the interviewer drilled me with hard questions about server management and refused to permit me to answer with the known solutions that I was aware of (checking server logs, configuration settings, etc.).

    Interview Questions

    • I was asked to describe what processes happen from initiation to page generation when an incoming URL executes on a server.   Answer Question
